SPECIFICATION forming part of Letters Patent No. 664,204, dated December 1 190 Application filed December 80,1899. serial No. 742,047. No model.)

To ctZZ whont it nutty concern:

Be it known that we, CHARLES M. WOOD, a resident of Slate Hill, in the county of Orange, and \VILLIAM J. BLAIR and JOHN A. WEB- sTER, residents of New York, in the county of New York, State of New York, citizens of the United States, have invented certain new and usefullmprovemen ts in Music-Leaf Turners, of which the following is a specification.

Our invention relates to improvements in music-leaf turners.

The object of our invention is a music-leaf turner in which the leaves are turned by a simple and compact mechanism which a performer sets in motion quickly and with little exertion. This object is attained by the means described in the annexed specification and illustrated in the accompanying drawings, in which-- Figure 1 is a view in front elevation of a music-leaf turner embodying our invention with the arms for turning the leaves of music in the released position which they occupy after the leaves have been turned by them, a part of the upper extension of the rack hav ing been removed and the parts brought together to economize space. Fig. 2 is a sectional view of the same, taken through line 00 w of Fig. 1. Fig. 3 is a central transverse sectional View, upon an enlarged scale, taken upon line y y of Fig. 1, the parts being shown in the position they would occupy when the arms are set preparatory to turning the leaves. Fig. 4 is a sectional view, upon an enlarged scale, taken through line 2 .2 of Fig. 1. Fig. 5 is a detail rear elevation of the horizontal arms pivoted upon the back of the rack.

Referring to the parts, which are indicated by similar reference characters wherever they occurthroughout the various views, the upper extension a of the rack A has a central vertical groove ct','which extends from the ledge (t for supporting the music to the top of the extension Ct. Upon the edge of the groove is hinged a spring-pressed metal strip B, beneath which the sheet of music to be performed is held. Strip B has a backward and outward extending arm or thumb-piece 1), against the under side of which presses a spring I). When it is desired to insert a sheet of music beneath the metal strip B or to remove a sheet therefrom, the strip is raised by pressing down on thumb-piece b.

Centrally secured to the rack, beneath the ledge a is a lug-plate O, which has two forwardly-projectinghorizontallugscc,between which are journaled disks c c and 0 upon a pin 0 These disks project back through a rectangular hole a in the rack. To each of these disks is secured a horizontal arm c c or c which terminates in a spring-finger c, 0 or c for grasping the leaves of music. The ledge C62 is recessed at a and at a to allow the fingers to come close to the rack. Each of the disks has in its upper face a cen- 65 tral receptacle for a coiled spring 0 c, or a. One end of the spring is secured to the disk and the other end enters a groove 0 in the pin The tension of the springs is regulated by turning the pin 0 with a screw-driver or other instrument and when the desired tension is obtained bringing the set-screw 0 to bear against pin c Upon the lower end of the back of the rack, opposite the disks c c and the arms 0 0 (1, are bars or arms D D D which are pivoted at one end upon a pivot D in a horizontal recess a in the rack and have their other ends curved down to a common plane and swiveled to rods or stems d cl 61 which project forward through perforations in the \lower end of the rack and terminate in keys or buttons 1, 2, and 3, respectively. Around the rods cl d (P, between the buttons and the rack, are coiled springs (7 d", and d which keep detents (1, (Z and d upon the rods d, d, and d in contact with the disks 0 c and 0 so that when the arms 0, c and c are turned back to their set position the detents are snapped into grooves c", 0 and c in the peripheries of the disks, as shown in Fig. 3.

In operation the arms 0, c and c are turned back in the direction of the arrow in Fig. 2 to their set position, as shown in Fig.

3, by grasping the finger-piece 0 which is secured to the arm a and extends beneath the arms c and a and the sheet having been placed beneath the spring-strip B the leaves to be turned are each placed in aspring-fingerc,

0 or c. Nhen ready to turn the first leaf,

the performer simply strikes button No. 1, which throws detent (1 out of the groove 0,

when the spring 0 rotates the arm a back, turning over the leaf. The second and third leaves are turned in a similar manner by striking buttons 2 and 3, respectively.

hat we claim is- 1. In a music-leaf turner the combination of a rack, means for holding asheet of music upon the front thereof, disks journaled upon the front of the rack, arms attached to the disks with fingers for grasping the leaves of the sheet, bars or arms pivoted upon the back of the rack for engaging the disks, keys in front of the rack for operating the bars the striking of which disengages the arms from the disks, and springs for reciprocating the disks after they are so disengaged from the arms, substantially as shown and described.

2. In a music-leaf turner the combination of a rack, means for holding a sheet of music upon the front thereof, disks journaled upon the front of the rack having arms with fingers for grasping the leaves of music and grooves in their peripheries for engaging detents upon arms upon the back of the rack, said arms pivoted upon the back of the rack having de tents for engaging said grooves and stems projecting forward through perforations in the rack and terminating in keys the striking of which disengages the detents from the grooves, and springs for reciprocating the disks when so disengaged, substantially as shown and described.

3. In a music-leaf turner the combination of a rack, means for holding a sheet of music upon the front thereof, a lug-plate secured upon the front of the rack, disks journaled upon a journal-pin between the lugs of said plate each having an arm for grasping a leaf of the sheet secured thereto and a receptacle in it for receiving a coiled spring, said springs one end of each of which is secured to its disk and the other end of which enters a groove in the journal-pin for reciprocating the disk,

and arms pivoted upon the back of the rack for engaging the disks having stems projecting through the rack and terminating upon the front thereof in keys the striking of which disengages the arms from the disks, substantially as shown and described.

4-. In a music-leaf turner the combination of the rack, means for holding a sheet of music on the front thereof, disks journaled upon the front of the rack having arms for grasping the leaves of the sheet and grooves in their peripheries, coiled springs in the disks for reciprocating them, arms pivoted at one end to the back of the rack having detents for engaging the grooves in the disks and swiveled at the other end to rods, said rods projecting forward through the rack and terminating in keys, and coiled springs upon the rods between the keys and the rack for keeping the detents upon the arms in contact with the disks, substantially as shown and described.

5. In a music'leaf turner the combination of the rack having a ledge at the lower end for supporting sheets of music and an upward extension with a central groove, a metal strip hinged to the edge of the groove having a backwardlyextending thumb-piece, a spring pressing against the under side of the thumbpiece to hold the strip down on a sheet of music inserted beneath it, horizontally-reciprocating arms for grasping the leaves of music, springs for reciprocating the arms, means for locking the arms, and keys the striking of which releases the arms, substantially as shown and described.
